The cost y (in dollars) to rent a lane at the bowling alley is proportional to the number x of hours that you rent the lane. It
Alika [10]

Answer:

a) y = 9x

b) For every increase of 1 hour the price to rent the lane increases by $9.

c) $27

Step-by-step explanation:

a) Since it costs $18 for 2 hours we can infer that for every 1 hour it costs $9.

So, the equation would look like this:

y = 9x

b) In this context, for every increase of 1 hour the price to rent the lane increases by $9. Like the question gave us, the price for 2 hours cost $18.

c) Plug 3 into the equation:

y = 9(3)

y = 27

Therefore, it costs $27 to rent the lane for 3 hours.

15. The container shown in the figure is filled with a liquid that weighs 50 g. Find its density.
3241004551 [841]

Answer:

  C.  0.006 g/cm³

Step-by-step explanation:

As the units tell you, density is the ratio of mass to volume. The volume of the container is found from ...

  V = πr²h = π(10 cm)²(25 cm) = 2500π cm³

Then the density is ...

  ρ = (50 g)/(2500π cm³) = 1/(50π) g/cm³

  ρ ≈ 0.006 g/cm³

_____

<em>Comment on the problem</em>

The "liquid" has about the same density as air pressurized to 75 psi.
